Using performance metrics

Select Performance in the OpsCenter Console to view these types of metrics:

Cluster Performance Metrics

Pending Task Metrics

Column Family Metrics

When you add a graph, you choose the Metric and the source that OpsCenter uses to collect the
data for the graph:

Cluster wide

All nodes

The node running Opscenter

Several commonly-used performance metrics graphs are displayed initially. Data appears in the
graphs after you set alerts.

You can save, delete, and choose the default view of graphs. Click the link to save presets at
the top of the Performance area. The Save, Delete,
and Make Default menu options are available after saving more than one
view.
